摘　　要：为了研究乌梢蛇Zaocys carinatus对食物的选择性,寻找最适宜的乌梢蛇幼蛇开口食物;为乌梢蛇专用人工饲料开发提供理论基础,通过对解冻和保鲜食物投喂观察,结果表明:乌梢蛇幼蛇开口率因食物种类不同有明显区别,对蛙类食物的开口率较高,为71.63%,对昆虫类食物开口率较低,为10%以下;在食物的选择性方面,幼蛇对蛙类食物选择率较高,为85.56%,对昆虫类食物选择率较低,为5%以下。Food feeding test with thaw food and fresh food was carried out to know about the diet selectivity, find out the most suitable food for young Zaocys carinatus and provide theoretical basis for the development of special artificial compound feed for Zaocys carinatus .The results showed that the aperture ratio of young snakes differed from food types, with higher aperture ratio to frogs (71.63%) and lower aperture ratio to insect food (<10%).In the aspect of food selectivity, the selection rate to frogs of young snakes(85.56%) were higher than that to insect food(<5%).
